Remote Park Assist User Interaction via Mobile Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote parking assist systems lack effective user intervention and management capabilities, particularly in detecting and validating parking spaces due to limitations in range detection sensors, which can fail to accurately determine the location and suitability of parking spaces.
Innovation Solution
A vehicle system that pairs with a mobile device to receive user input on potential parking spaces, displaying virtual representations of the vehicle and surroundings, allowing users to select and validate parking spaces, and enabling autonomous movement along calculated paths with continuous user input validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the RePA system relies solely on range detection sensors to automatically detect parking spaces, then the automation level is improved, but the measurement precision and reliability of parking space detection deteriorate when sensors fail to accurately determine location and suitability
Solution Approach 1:
The mobile device serves as an intermediary between the user and the vehicle's RePA system. It displays virtual representations of the environment, receives user inputs about parking spaces, and transmits this information to the vehicle. This mediator allows user expertise to supplement automated sensor limitations, improving detection accuracy while maintaining automation benefits.
Solution Approach 2:
The system implements feedback loops where the mobile device continuously receives sensor data, displays virtual representations to the user, and allows users to provide corrective inputs about detected parking spaces. This feedback mechanism enables real-time validation and correction of automated detection, improving measurement precision through human-in-the-loop verification.
2Ease of operation
If the system provides comprehensive user intervention features for managing autonomous parking maneuvers, then the ease of operation is improved, but the device complexity increases due to additional communication and display components
Solution Approach 1:
The mobile device leverages its existing multi-functional capabilities (display, touchscreen input, wireless communication) to serve multiple purposes: showing virtual environment representations, receiving user inputs about parking spaces, transmitting control signals to the vehicle, and providing training modes. This universal use of existing components provides comprehensive user intervention without proportionally increasing system complexity.
3Ease of operation
If the mobile device provides training modes and detailed visual guidance for first-time users, then the ease of operation is improved, but the loss of time increases due to additional training and validation steps
Solution Approach 1:
The system dynamically adapts its operation mode based on user experience. It provides comprehensive training modes with detailed visual guidance for first-time users, then transitions to more efficient operation modes for experienced users. This dynamic adjustment optimizes the balance between ease of operation and time consumption, allowing users to benefit from guidance when needed while reducing time loss through familiarity with the system.

AI summary
Vehicle systems include features for performing remote park assist (RePA) operations. One system include a feature where a user provides a continuous input via a touchscreen on a mobile device. The mobile device transmits a message and a vehicle autonomously traverses a calculated parking path while the message is being received by the vehicle. Another system include a feature where the vehicle autonomously move to a parking space based on data received from the mobile device. The mobile device receives user inputs on a display showing representations of the vehicle and its surrounding areas to generate the data. Another system include a feature where the mobile device determines whether the user is a first time user of a RePA application. The mobile device operates in a certain training mode based on the determination.
